C. Thyroid cancer
D. Liver cancer
Which is the most common primary malignant intraocular tumor?
A. Intraocular lymphoma
B. basal or squamous cell
C. Retinoblastoma
D. Choroidal melanoma
Innermost layer of the choroid-
A. Haller’s layer
B. Sattler’s layer
C. Choriocapillaris
D. Bruch’s membrane
ALL of the following are correct about arteries of the uveal circulation EXCEPT –
A. Supply outer layers of the retina
B. Branches of the ophthalmic artery

Choroid layers -Outermost to Innermost
- Haller’s layer – outermost layer of the choroid consisting of larger diameter blood vessels
- Sattler’s layer – layer of medium diameter blood vessels
- Choriocapillaris – layer of capillaries
- Bruch’s membrane – innermost layer of the choroid
Most common primary tumours to metastasise to the eye are from –
- Breast (47%),
- Lung (21%),
- Gastrointestinal tract (4%)
Bilateral, multifocal metastases are most often secondary to breast cancer
Unilateral, unifocal metastasis are more commonly found with lung cancer.
